at the top ; the upper two-thirds of the first and third transverse 

 cubital nervures are obliquely bent ; the first recurrent nervure is 

 received shortly beyond the transverse cubital ; the lower part of the 

 apical abscissa of the radius is oblique, the upper straight ; the outer 

 branch is shorter than the lower part. 



Palarus lineatifrons, sp. nov. 



Black ; the inner eye orbits broadly below, narrowly above, 

 antennal keel, a mark, roundly dilated above, in the centre of the 

 face below, clypeus, base of mandibles broadly, a line on the hinder 

 edge of the pronotum, the base of the propleurse — the mark roundly 

 incised at the apex — a curved mark on the apex above, tegulse, a 

 mark in front of them, reaching to the lower edge of the mesonotum, 

 a small oblique mark on the base of the mesopleurae above, a large 

 mark on the base extending from the top to below the middle, 

 broadest above, rounded below, the base of the metapleurae, the line 

 irregularly waved on the apex, an irregular mark behind the spiracles, 

 a large mark on the apex, its lower half irregularly dilated back- 

 wards, two lines on the base of the scutellum and the post-scutellum, 

 pale yellow ; the first abdominal segment rufous-yellow, with a 

 somewhat triangular mark in the centre at the apex ; the second to 

 fourth segments broadly from behind the middle, the lines dilated at 

 the sides, a narrower line not dilated laterally and almost separated 

 in the middle, the basal two ventral segments, except broadly in the 

 middle, the apices of the others narrowly and irregularly, yellow 

 with a rufous tint. Legs yellow, the greater part of the coxae, the 

 trochanters, the base of femora all round, their upper part broadly, 

 and the tibiae behind, black. Wings clear hyaline, the nervures 

 testaceous. 2 •

Cape Colony. Somerset East. 



Pygidium stoutly, regularly longitudinally striated to near the 

 narrowed apex, which is hollowed. Eyes distinctly converging 

 above, separated there by fully the length of the third and fourth 

 antennal joints. Frontal keel stout, long, rounded above, narrowed 

 towards the apex. Anterior ocellus large, wider than long, widely 

 separated from the posterior. Vertex closely and strongly punc- 

 tured, the front not so closely nor so strongly, the clypeus sparsely 

 punctured. Mandibles rufous in the centre. The whole head is 

 thickly covered with longish white hair. Pro- and meso-thorax 

 closely and strongly punctured, shining and thickly covered with 

 white pubescence. Scutellum sparsely punctured at the base and
